虛擬叢集客製化與效能分析

雲端運算旨在整合虛擬化技術與服務導向架構而形成的一種運算與服務架構，藉以提供資源動態擴充以及虛擬化的服務。雲端運算主要的優勢之一是可以讓不同規模的企業或應用根據實際需求，快速、經濟、及動態的取得並管理所需的基礎設施，包括計算、儲存、網路等IT資源。近年來，由於資料密集型的應用需求大增，硬體成本與能源消耗的問題，已被視為邁入下一個世代雲端運算最重要的課題之一。為此，虛擬化技術更被視為降低硬體成本與減少能源消耗最重要的技術。本論文提出一個虛擬環境的管理平台，目的在提供不同領域的使用者，客製化雲端運算環境，藉以提高使用者的自主性與便利性。透過實際的佈署，我們比較各種軟硬體、管理平台以及虛擬化技術的效能。實驗結果所獲取的數據與經驗，可以讓使用者在環境的選擇上有個依據。此外，我們也透過實驗來驗證各種不同虛擬機佈署策略的效能差異，讓環境管理者在建置虛擬機環境上知道如何發揮最大的實體機器效益，減少資源的浪費，達到減少成本的目的。

Cloud computing integrates virtualization technology and service-oriented architecture, forming a new computing and service model, to provide dynamic, scalable and virtualized resources. One of the main advantages is that businesses (or applications) can rapidly, economically and dynamically obtain its required IT resources based on the actual demand. In recent years, due to the significant increase of data-intensive applications, the hardware cost and energy consumption, have been regarded as one of the most important issues for the next generation cloud computing era. To this end, virtualization plays as key enabling technology towards cost optimization and energy efficient. This paper introduces a customizable virtual machine management system (CVMS), which aims to efficiently provide cloud platforms that are suitable to individuals and enterprises. Given that the virtual platform is customized system, its autonomy and performance will be further enhanced. To evaluate the performance of the proposed architecture, we have deployed various systems with different hardware, software and virtualization techniques. Experience and performance profiling obtained from the experiments can benefit users in selecting cloud systems that are suitable to their applications. For datacenter, effectiveness of different virtual machine deployment strategies were also reported to facilitate cloud providers managing their resources in an economic manner.
